This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

Although dark matter is a central element of modern cosmology, the history of how it became
accepted as part of the dominant paradigm is often ignored or condensed into an anecdotal …

A bstract We show how several properties of the QCD axion can be extracted at high
precision using only first principle QCD computations. By combining NLO results obtained in …

In the late 1970s, the axion was proposed as a solution to the strong CP problem, ie, the
puzzle why the strong interactions conserve parity P and the product CP of charge …

For centuries the heavens have been a natural laboratory to test the classical laws of motion,
and more recently to test Einstein's theory of gravity. Today, astrophysics has become a vast …

We review physics of light pseudoscalars (axions, majorons and familons) and their effects
in cosmology. The axions which solve the strong CP problem play important roles in …

The nature of dark matter and properties of neutrinos are among the most pressing issues in
contemporary particle physics. The dual-phase xenon time-projection chamber is the …

Photons can mix with low-mass bosons in the presence of external electromagnetic fields if
these particles—not necessarily of spin 1—couple by a two-photon vertex. Important …

We report on the results from a search for dark matter axions with the HAYSTAC experiment
using a microwave cavity detector at frequencies between 5.6 and 5.8 GHz. We exclude …

Various extensions of the standard model of elementary particle interactions predict the
existence of new particles such as axions, or “exotic” properties of known particles such as …
